Answer:
3. into ice, which is denser than liquid water.
Explanation:
Water molecules are held together by hydrogen bonds. The bonding is usually between the hydrogen atoms of one water molecules, and oxygen atom of neighboring water molecules. Structurally, both oxygen and hydrogen atoms pulls the electon towards themselves.Thus both atoms share electron by covalent bonding.
However, because oxygen has a strong positively charged nucleus it pulls the electron more to itself than oxygen. Thus oxygen is partially negative and oxygen is partially positive. This interactions take place among all the oxygen and hydrogen atoms in water molecules. . The unequal charge distributions is called dipole and the attraction between oxygen and hydrogen is called hydrogen bonding .
The orientation of hydrogen and oxygen molecules from dipole -dipole interactions of hydrogen bonding makes the oxygen and hydrogen atoms in ice to be pushed apart well spaced out in ice, making them less dense than liquid water where they were aggregated. Thus from the question option C is correct.
Answer:
B. Different genes are expressed due to their environment.
Explanation:
I think it's this one because it makes the most sense, but I'm still not sure sorry
Answer:
It occurs to create innovation in the existing technology.
Explanation:
A technological advancement is an attempt to develop current materials, devices, products or processes by further understanding of science. technological advancement provides innovations of existing technology or formation of new technology in order to better the life style and make easier our work. If the technological advancement did not occur, we are unable to increase efficiency of various instruments and machines.
